Coil problem - I think

I have a 96 sltx 1050 that has been giving me problems all summer. It finally quit. I had the coil tested and the results were: Primary tests - 0.7, supposed to be 0.35 and secondary was open - supposed to be 1550 ohms. It is coil #4060153. Is there anything other than a bad coil that woud cause this? The cdi and stator have been updated.Thanx for any help,Ross

If the secondary was tested directly at the coil (not through the plug wires and ground circuits)-than yes, it needs a new coil.
All 3 cylinders do share the black wire-maybe double check that wire is not damaged between the connecter and coil-otherwise it's serviced as a coil assembly.

Unfortunatly it looks like Polaris isn't selling any of the 3 cyl domestic coils,they sold for around $150 new.
